Specifically, the AP article relays information provided by NASA. It states,

The Near Earth Object Program.
Also, go to NASA JPL’s
Asteroid Watch for much more information on Earth threatening asteroids.
To find out the potential risk from asteroids, go to the NASA
Sentry Risk Table.
It states,
“The following table lists potential future Earth impact events that the JPL Sentry System has detected based on currently available observations….”
The JPL Sentry System “
… is a highly automated collision monitoring system that continually scans the most current asteroid catalog for possibilities of future impact with Earth over the next 100 years….”
